Einstein, Podolsky, and Rosen brought up a state with momenta of two particles anticorrelated, which introduced the concept of entanglement and excited many interesting studies. In contrast, we propose an experimental scheme to prepare and identify two-photon momentum positively correlated entanglement state (MPES) via Hong-Ou-Mandel interference and correlated imaging. Experimental data show that two photons are highly entangled with the transverse momenta of them positively correlated. Thus two-photon MPES has been achieved, and further investigations in properties and applications of two-photon momentum entanglement become possible.
